SPAClNG-TABLE FOR PUNCHING-NIACHINES.

SPECIFICATION forming part of Letters Patent No. 792,457, dated June 13,1905.

Application filed December 26, 1903. Serial No. 186,725.

To all 7071,0771 7'75 may concern:

Be it known that we, JOHN V. W. REYNDERs and \VILLARD T. SEARS, citizensof the United States, residing in Harrisburg, Dauphin county,Pennsylvania, have invented certain Improvements in Spacing-Tables forPunching-Machines, of which the following is a specification.

Our invention relates to certain improvements in attachments formachine-tools; and it more particularly consists in a novel device forintermittently and automatically feeding a plate to a punching-machineor to any machine performing a number of operations on the piece ofmaterial operated on.

One object of our invention is to provide mechanism which shall hold andautomatically feed a sheet of material to a continuously-operating punchor other machine, as indicated above,in such manner that holes will beformed in said sheet at previously-determined interyals.

A further object of the invention is to provide a work-feeding tablewhich shall be antomatically fed forward after each operation of thetool with which it is used and that by the action of said tool itself.

It is also desired to provide means which shall be capable of feeding apiece of material to a punching-machine in such manner that saidmaterial shall be automaticallymoved for variable though predetermineddistances.

Another object of the invention is to so support a carriage for holdingand feeding material to a machine of the character above noted that whendesired said carriage may be moved out of the way and the machine usedindependently of the same without interference from thecarriage-supporting structure.

An additional object of the invention is to provide a work-holdingcarriage having upon it means driven directly from the punch, whichshall make a stroke of fixed length, in combination with means forautomatically transforming this action, so that the carriage may be madeto move through any desired succession of variable distances.

These objects we attain as hereinafter set forth, reference being had tothe accompanying drawings, in which Figure 1 is a side elevation of aportion of our invention, indicating the punch and showing the positionof the carriage-track and its supporting structure relatively thereto,the figure also showing our improved work-holding carriage andillustrating a portion of the mechanism thereof in section. Fig. 2 is anend elevation of our improved carriage or spacing-table, showing thesupporting-track thereof in section and illustrating in detail the meansfor supporting a plate of material operated on. Fig. 3 is an endelevation of the auxiliary carriage and the supporting structuretherefor. Fig. 4 is a plan view showing our improved work-holdingcarriage or spacing-table. Fig. 5 is an enlarged plan view showingcertain of the details of our invention, it being noted that detailarrangements of certain of the parts in this figure are slightlydifferent from those shown in the other figures. Fig. 6 is a sectionalelevation showing the detail construction of the cylinder and itsadjacent parts as illustrated in Fig. 5. Fig. 7 is a sectional plan viewof a portion of the cylinder, on an enlarged scale, the same being takenon the line 7 7, Fig 6; and Fig. 8 is a side elevation of thetempletfeeding mechanism.

While we have illustrated our invention as employed in connection with apunching-ma chine and in the specification have so described it, it isto be understood that we do not limit ourselves to such a use, since itis obvious that our improved carriage or spacing-table may beadvantageously employed with any machine requiring a piece of materialto be periodically fed to it.

In the above drawings we have shown our device as designed for use inconnection with a continuously-operating punch, and it will beunderstood that the function of our improved work -holding carriage isto intermittently. feed a plate of material to said punch, moving itforward automatically after each stroke of the punch for any desireddistance, as predetermined by a templet.

Referring first to Figs. 1 to at, inclusive, we have indicated a punchat A, the plate of material to be operated upon being shown at 1/. asheld by clamping-jaws It, which engage it at one end, and by jaws a),which engage it at the opposite end. \Yhilc the first pair of jaws arecarried by the spacing-carriage in the manner hereinafter described, thejaws n are supported from an auxiliary carriage B, which consists of arelatively light framework supported so as to overhang the desired lineof motion of the plate to be punched by means of any desired number ofstandards B, upon which are fastened a series of tracks 7), l), and 7).

There are suitably-prejecting arms 6, l)", and 6" upon thecarriage-framework, provided with rollers 6", bearing, respectively,upon the above-n1enti0ned tracks in such manner that the outward sidethrust of the carriage is transmitted to and taken by the track 7/, thedownward thrust of the carriage by the track 6, and the inward sidethrust of the carriage by the track The clamping-jaws u. of theauxiliary carriage are supported from a pair of movable pieces a", whichcan be adjusted upon the overhanging arm B of the carriage by means of ahand-wheel a, which is connected to said pieces by means of any desiredforms of mechanism well known to theart or, if desired, by that form ofclamping mechanism shown in our pending application for patent, SerialNo. 175,663, filed October 3, 1903, for patent on an improvedspacing-table for punching-machines. The clamps u/ are, like the clampsa, provided with a hand-wheel a and connecting mechanism, whereby theymay be simultaneously moved toward and from one another. The plate a isprovided with any desired number of supporting devices, preferably ofthe form shown in Figs. 1 and 2, in which L is a standard havingbearings for a spindle to which are keyed one or more arms l, carryingat their ends rollerwheels Z. Said arms are yieldingly pressed upward bymeans of a spring W, carried upon a supporting-rod on the standard,which spring engages the end of an arm Z also keyed to the spindle Bymeans of a nut Z the position of the spring I may be adjusted so as toelevate or lower the roller-wheel Z, while by means of nuts the amountof compression of the said spring maybe varied so as to exert greater orless pressure upon the wheel in order to suit the weight of the plateoperated upon.

Referring to Fig. 1, we have shown in dotted lines a wheel C, which isso connected to the punch-driving mechanism that it is given onecomplete revolution at each complete reciprocation of the punch. Meshingwith this gear-wheel is a second wheel C, fixed upon a shaft 0, having abevel-pinion c, which meshes with a second bevel-pinion c upon a shaft0. Said latter shaft is carried in any convenient form oftumbler-bearings supported from a series of standards D, which areplaced at intervals on the side of a punch opposite to that having thestandards B. Splined to the shaft c is a slidable sprocket-wheel c,which is so constructed as to be moved with the spacingcarriage E andfrom which is driven the mechanism on said carriage. Extending betweenthe standards I) are three tracks (Z, (Z', and (.Z, with which engagerollers (i (F, and d, journaled on the carriage E in such manner as toeffectively take the side and downwardlyacting thrusts of the carriageE. In addition there is a fourth track a, which is provided with teethfor engagement by a foot f, having similar teeth and pivotally connectedto a cylinder F, hereinafter described. There is also a rack 0'supported by and extending between the standards I), there being on thecarriage E a gear-wheel a, meshing with the same. Journaled in suitablebearings upon the carriage E is a shaft 0 extending parallel with theshaft 0 and having on it a sprocket-wheel a", operativel y connected tothe sprocket-wheel a on said shaft by means of a chain 0 The shaft 0serves to turn, through the medium of a pair of beveled gear-wheels anda, a shaft, upon which is carried a cam G, having in its face aneccentric groove, as indicated in dotted lines in Fig. 1.

Referring now to the enlarged view shown in Fig. 5, it will be seen thatthere is a lever 7, carrying a roller 0', which enters the eccentricgroove of the cam Gr, one end of said lever being pivoted to a linkwhich movably supported upon an extension of the shaft carrying thecam-wheel G, while the second end of said lever engages a cross-headupon a piston-rod g. This rod, as shown in Fig. 6, has fixed to it apiston g, which operates within the cylinder F, there being an extension7 to said rod projecting from the opposite face of the piston. The saidcylinder has projecting fromit the portion indicated in dotted lines atF in Fig. 5, which portion is engaged by guides I) on the framework ofthe carriage E in such manner as to permit motion thereof relatively tothe carriage in a line parallel to the longitudinal of said cylinder.The cylinder F is provided with stuffing-boxes f and f for the passageof the piston-rod and its extension and, as shown in Figs. 6 and 7, haspassages f and f" extending from its ends into a valve-chest F. Thereare two openings in the valve-chest connecting the ports f and f, havingvalves, one of which is so placed, as indicated at f, as to be held toits seat by pressure exerted in the portf, while the other valve 7 is soplaced as to be pressed to its seat by pressure exerted in the port f.These valves are loosely carried by headed valve-rods f" and f'",respectively, both of which pass through stuffing-boxes, as shown. Thero if has upon it a spring f, extending between the stuffing-box glandand a pair of nuts adjacent to its end, there being, as shown in Fig. 5,a projecting stop (2 so placed upon the carriage E as to engage the endof the said rod f ata definite point in the stroke of the cylinder. Thevalve-rod f also has a spring f, held in place by a pair of nuts, and inaddition carries upon its end a piece f, preferably of an L shape, itbeing noted from Fig. 6 that there is upon the cylinder a projecting armcarrying an adjustable screw f so placed as to engage thedownwardly-projecting part of the piece f This piece f carries arelatively thin rearwardly-projecting plate f designed to coact with aseries of stop-plates carried by a templet-wheel H, there being one ofsaid plates shown at it in Fig. 5. Said templet-wheel is carried upon ashaft supported in suitable bearings on the carriage E and is providedwith some form of mechanism so constructed as to turn it to the extentof the angle occupied by the end of one stopplate after eachreciprocation of the punch or after each forward movement of thecarriage. In the presentinstance a worm-wheel h is fixed to thetemplet-wheel shaft, and this is engaged by a worm 7L2, carried on ashaft driven from a bevel gear-wheel it through a bevel-pinion 70 Ashaft it, revolved in any desired manner from the shaft 0 is providedwith a cam 72 and this engages a roller carried by one end of a lever h,the other end of said lever having a pawl 7L" constructed to operativelyengage the teeth of a wheel 7L fixed to the bevel-gear 7t" when saidpawl is moved in one direction and to slip over said teeth when it ismoved in the opposite direction. It will be understood that thestopplates h are held to the periphery of the templet-wheel H, so thatas said wheel is turned the various stop plates are successively broughtin line with the platef carried by the valve-rod f Bolted to thecylinder F is a piece f, which is forked for the reception of thetoothed foot f, this latter being pivoted to it so as to be free to movein a vertical plane. Upon the rear face or end of said foot are two flatsurfaces f at an angle to one another, and there is a spring-pressedplunger f, carried by the piece f, so as to engage either one of saidtwo faces, and thereby tend to keep the toothed foot either in theposition shown in Fig. 6 or in an elevated position at an angle to thehorizontal.

In addition to the various parts described above it will be noted thatthere are various electrical connections shown on the carriage as wellas trolley-wires, which, since they form no part of the structureclaimed in the present application, but have been covered in a companionapplication for patent, Serial No. 186,175, filed December 22, 1903,have not been shown nor described in detail.

In addition to the shaft 0, which, as before described, is connected tothe piston-rod g", there is a shaft 1, which is preferably driven fromthe punclroperating mechanism by any convenient gearing, (not shown, andsimilarly to the shaft 0 is supported in tumbler-bearings upon thestandard Gr. Splined to this shaft is a spiral gear 2', which mesheswith a second spiral gear 5, fixed to a shaft, which also carries abevel-gear 2' Said bevel-gear transmits power through a bevel-gear 2' ashaft 6*, and a bevel-pinion to a second bevelpinion j, keyed to a-shaftJ. Also fixed to said shaft is one of the members of a frictionclutch,whose second member is fixed to a sleeve f, revohible upon butindependent of the shaft J and having fixed to it a spiral gear-wheel7". This latter in turn meshes with a second spiral gear 1', which isfixed to a shaft, also having keyed to it a gear-wheel 0 which mesheswith the rack a, as above noted.

An operating-handlej has connected to it a forked arm one end of whichis shown in Fig. 5 as engaging a collar on the movable member j of thefriction-clutch for throwing said member into and out of engagement withthe fixed member thereof, and there is in addition a hand-wheel 7'having connected to it a gear-wheel 7' Which meshes with a secondgear-wheel j" on the same shaft as that having the spiral gear f.

In operating the above apparatus the cylinder F, as well as the ports fand f*, is filled with oil or some other incompressible fluid, and aslong as the valves f and f remain seated the cylinder will be compelledto move on its guides whenever the piston-rod g", and consequently thepiston 9 is moved. Prior to starting the machine a number of stop-platesare fixed in position upon the templet-wheel H, it being understood thatthese plates are of lengths bearing a definite relation to the. spacesthrough which it is desired the carriage, and consequently the pieceheld thereby, is to be moved between each stroke of the punch. As abovenoted, the shaft 0 and also the sprocket 0" are turned by thepunch-operating mechanism through the gear-wheels C and O, shaft 0, andbevel gears c and 0 From said sprocket-wheel 0 power is transmittedthrough the chain 0 sprocket-wheel e", shaft 0 bevel-pinions e and e tothe cam G, which through the link g reciprocates the piston-rod g andthe piston 9 once for each reciprocation of the punch. 1f now the pistong be in the end of the cylinder opposite to that in which it is shown inFig. 6 and the pistonrod be moved in the direction of the arrow, thecylinder F will be moved bodily in the same direction, since there is noWay by which the fluid can pass from one side of the piston to theother, the spring f being sufliciently strong to keep the valve f seatedin spite of the pressure in said cylinder. Owing to the shape of theteeth upon the foot f, this latter will when the cylinder is moved beturned upon its pivot to a slight extent, so

as to permit it to slip over the teeth upon the track (2. The movementof the cylinder and' its attached parts will continue until one of thestopplates 7t upon the templetwheel H engages the plate f, carried bythe piece f on the valve-rod f", at which time the spring f on said rodwill be compressed as this latter is moved longitudinally, so that thepressure of liuid in the cylinder will cause the valve f to open, thusallowing said fluid to pass from one end of the cylinder to the otherand permitting the valve-rod 7, with the piston to complete their strokewithout further motion of the cylinder and its toothed footf. As thepiston-rod and piston begin their return stroke the spring-pressedplunger f, aided by gravity, causes the toothed footf to engage thetoothed track a, and since, as before, both valves f and f are closedthere is no passage of the fluid in the cylinder from one end thereof tothe other. Consequently the carriage as a. whole, with the plate a to beoperated upon and the auxiliary carriage B, will be moved in thedirection of the arrow in Fig. 1. Such motion will continue until theend of the valve-rod f is engaged by the stop 0 on the carriage,

which causes said rod to be moved sullieiently to permit the valvef toopen. This again allows fluid to pass from one end of the cylinder tothe other and permits relative motion between the piston g" and the saidcylinder, so that while the said cylinder and carriage remain stationaryrelatively to the track 0 the piston 7 again moves to the right-hand endof the cylinder, after which the above-described cycle of operations isrepeated. During the interval between the time that the cylinder hasstarted to move away from the templet-wheel and the time when it isagain moved into aposition ready to engage one of the stop plates onsaid wheel the feeding mechanism (shown in Fig. 8) has caused the wheelto be turned to an extent suiiicient to bring a second stop-plate inline with the plate f, carried by the valve-rod. f it being furthernoted that the movement of the device is so timed that the punchoperates upon a plate It at some time other than when the carriage 1G isbeing moved.

As shown in Fig. 2, there is a hand-operated clutch K, by which theshaft 0 may be operative] y connected to or disconnected from thedriving mechanism of the punch, and if the lever Z, by which this clutchis operated, be so thrown as to disconnect the said shaft from saidmechanism the hand-wheel may then be operated to traverse the carriageat will. If it be desired to quickly move said carriage, the handle j isthrown so as to operatively connect the two members 7" and j of thefriction-clutch, in which case power is transmitted "from the shaft 1,through the spiral gears and 21, through shafts 9" and J to thefriction-clutch y" f, spiral gear-wheels j and to the spur-wheel owhich, meshing with the rack 4, will cause motion of the car riage at arelatively high rate of speed.

As previouslyindicated, the detail mechanism for regulating the strokeor distance moved through by the carriage, and consequently the workheld thereby, at each opertion of the punch may be widely varied withoutdeparting from the n'iain idea of our invention. For example, ifdesired, such parts may be constructed and arranged as indicated inFigs. 1, 2, and 4, in which is shown a construction accomplishing thesame object as is attained by the revolving templet-wheel and stopplatesshown in Fig. 5.

As shown by Fig. 2, we provideagrooved portion M, in which may befastened stops in, arranged i n the grooves at any desired distancesfrom each other. lt will be understood that one groove with its seriesof steps may be employed, although in the case illustrated we have showntwo grooves with the stops placed in staggered positions, so that it maybe possible for them to be engaged by the stopping mechanism even thoughthe distance between two consecutive stops be very short. In thisarrangement of templet we provide an arm at, lixed to a shaft whose endportion is shown at m" and which carries a pair of arms 7M3 for engagingwith the stops in. The end of the piston-rod f has fixed to it anadjustable arm 9, having at the end a portion so placed as to trip thearms M and cause them to be disengaged from the stops in, as shown inFigs. 2 and l.

From the above it will be seen that we provide means by which a plate orother piece of material will be automatically fed to the machine whichis to operate upon it and by automatic mechanism regulate this feedingso that it occurs for any predetermined variable distance and atpredetermined times. .It will further be seen that if it be desired touse the punch without the carriage this latter may be removed altogetheror run to the extreme end of its track, so that there will be nothing tointerfere with the free operation of the machine, since it will be notedthat both sets of the standards l) and B are at a relatively greatdistance to the rear of the punch.

\Vhile we have shown our preferred device for automatically regulatingthe amount by which the work-holding carriage is fed forward after eachstroke of the punch, it will be understood that this same end may beaccomplished by other devices which are merely the mechanicalequivalents of that shown.
